Described cushion pad is rubber or urethane pad.
The invention has the beneficial effects as follows,
1. concrete bridge case couples together multiple concrete bridge casees by interior cushion pad, outer cushion pad and the screw mandrel mode that is flexible coupling, the mode that is flexible coupling by inside and outside cushion pad is connected concrete pontoon bridge with pile, solved wave to bridge case impact moment to the damping of shocks of bridge case be firmly connected the damage that concrete tank wall is caused, and outward appearance is also more attractive in appearance beautiful.
2. polystyrene foam plate unit weight density is 18 ㎏/㎡, takes more than 2 machine-shaping cystosepiment to become inner membrance, improves the intensity of cystosepiment, ensures the geometry of inner membrance.Thereby because polystyrene foam plate in bridge case combines closely concrete and cystosepiment as inner membrance, cystosepiment is completely filled out and in bridge case, is made bridge case without any hole, even if concrete cracking seawater also cannot enter in bridge case.
3. realize by the bridge body structure of beam, plate, post the structural strength that alleviates the weight of bridge case and improve bridge case, solve preferably the fixing needed structural strength between main bridge bridge case and main bridge bridge case, auxiliary bridge bridge case and auxiliary bridge bridge case, auxiliary bridge bridge case and main bridge bridge case, main bridge bridge case and pile gripper, pile gripper and pile.
4. concrete bridge case is the concrete bridge case that cement, breeze, flyash, anti-crack fiber, high efficiency water reducing agent, sand, stone, water are mixed, and concrete bridge case strength grade is C35-C55.Greatly improve concrete cracking resistance contraction, decay resistance and concrete water resistance by changing concrete material composition and grating.
5. main bridge bridge case, by the fixing pile gripper mode of roller level, better solves the wearing and tearing of pile gripper to pile, improves the application life of pile and pile gripper.
6. the reinforcing bar in concrete bridge case is Epoxy Resin Coated Steel Bars.Solve the corrosion of penetration of sea water to reinforcing bar and because corrosion of steel bar expands concrete destruction, improved greatly the concrete life-span by epoxy coating.
7. bridge case handling mode is permanent anchor hawser stake, reduces handling difficulty, saving fund.
8. impregnating with silane anti-corrosion material has excellent repellency and anti-chloride ion permeability, and UV stable reduces weathering and damages, and reduces the advantage of freeze thawing infringement and seawater chloride permeability.
9. the employing of concrete bridge case, shortens cost, duration, and in bay, floating harbour concrete pontoon bridge can move as required.
10. the employing of concrete bridge case, because own wt increase makes it have good anti-ripple stability, strengthens the frictional force of security performance enhancing and bridge case channel surface, and the sliding danger of falling water of user reduces.
The employing of 11. concrete bridge casees has fabulous tolerance to cause thermal damage in the time catching fire.
